GeForce 810M vs Radeon R9 270X

Intro

Compare those specifications to the Radeon R9 270X, which has a clock frequency of 1000 MHz and a GDDR5 memory frequency of 1400 MHz. It also makes use of a 256-bit bus, and uses a 28 nm design. It is comprised of 1280 SPUs, 80 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 810M		15 Watts
Radeon R9 270X		180 Watts
	Difference: 165 Watts (1100%)

Memory Bandwidth

Theoretically speaking, the Radeon R9 270X should perform quite a bit faster than the GeForce 810M in general. (explain)

Radeon R9 270X		179200 MB/sec
GeForce 810M		14400 MB/sec
	Difference: 164800 (1144%)

Texel Rate

The Radeon R9 270X will be quite a bit (about 1255%) more effective at anisotropic filtering than the GeForce 810M. (explain)

Radeon R9 270X		80000 Mtexels/sec
GeForce 810M		5904 Mtexels/sec
	Difference: 74096 (1255%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon R9 270X is the winner, and very much so. (explain)

Radeon R9 270X		32000 Mpixels/sec
GeForce 810M		2952 Mpixels/sec
	Difference: 29048 (984%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of information (measured in MB per second) that can be moved across the external memory interface within a second. It is worked out by multiplying the interface width by its memory speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
